An input force of 7 n is applied to a machine with a mechanical advantage of 1.75. what is the maximum the machine could lift? 12.25 n7n7.25 n26.2 n

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

Ionic compounds can be readily dissolved in water because the high dielectric constant of water screens and decreases the force between the oppositely charged ions.
